AIRSHIP.

pecification of Letters ratent;

Application filed September 2, 1910. Serial No. 580,200.

a detail of the catch; and Fig. 3, a section on the line 3-3 of Fig. 2.

Like parts are indicated by like letters in all the figures.

A is the frame work of the air ship upon which is mounted the A-frame Acarrying at its apex the drive shaft A upon which is rigidly mounted thedriving gear A. The bell crank lever A is rotatably mounted about thedrive shaft A and carries the bearings A, A, in which is mounted thehaving the gear A in engagement with the gear A and having at the otherend the propeller Af. The quadrant A rigidly mounted upon the A- frame Ais provided with the notches A to engage the locking mechanism Acontrolled by the handle A upon the lever A. The bearings B, B rigidlymounted upon the A-frame A carry the shaft 13 having at one end the gearB in mesh with the gear A and at the other end the propeller B. Thecollars 13 upon the shaft 13 engage the propeller shaft A pawl 13carried by the lever B which is in engagement with the quadrant B havingthe notches B adapted to be engaged by the catch B controlled by thehandle B upon the lever B. The lug C mounted upon the frame A, carriespivotally mounted therein the two jaws Ct, which are provided with thecylindrical bearings C and have the upwardly extending points C Thesprings C engaging the lug 0 force the aws C together to grip the shaftA".

I have shown in-my drawings an operative device, but it Wlll, of course,be e'yiing screw is dent that many changes might be made in the size,shape and arrangement of parts without departing materially from thespirit of m invention and I, therefore, wish that my I rawings beregarded as in a sense diagrammatic.

The use and operation of my invention are as follows :When the ship isto be operated, the drive shaft is driven in any suit-- able manner froman engine not shown, carrying with it the main driving gear. Thecombined lifting and propelling screw is moved into the upper or liftingposition and the gear which drives the auxiliar liftthrown into mesh witthe driving gear. The combined force of the two screws is thus used toraise the ship perpendicularly from the ground. After the ship hasreached the desired height, the

position of the combined propelling and lifting screw is changed untilthe propeller shaft assumes a horizontal rather than a verticalposition, at which point it acts as a. propelling screw. The verticalposition of the ship may then be controlled by the auxiliary liftingscrew which may be thrown out of operation when a descent is to be madeor thrown into operation when an ascent is to be made.

I claim 1. In a flying machine a frame, a transversely disposed drivingshaft and a driving gear thereon, a controlling lever rotatably mountedon the driving shaft, an arm projecting at right angles from said lever,bearin s at both ends of said arm and a propel er shaft rotatablymounted in said bearings, a propeller at one end of said shaft and apinion adjacent the other end in mesh with said driving gear, a liftingpropeller, a-s'haft therefor, a pinion carried thereby in opposition tothe driving gear and means for holding said pinion in mesh with'l'andout of mesh with the driving gear.

2.;In a flyin machine a frame, a transversely dispose driving shaft anda driving ear thereon, a controlling lever rotate-bly mountedonihmdrivinshaft, an arm projecting at righf an'gles" rom said lever, bearings atboth ends of said arm and a prowith said driving gear, a lifting(prapeller,

peller shaft rotatably mounted in said out of mesh with the driving gearand bearings, 11 pro eller at one end of said shaft means for holdinsaid propeller shaft in a and a pinion a jacent the other end in meshvertical and in a orizontal position. v w M J OHN G. BAUER.
